Illu): Y n

x IIIA i From the foregoing it will be seen that the protectorl may be readily applied to or removed from the tire. Then it is desired to apply it, it is only necessary to place it over the outer tube or casing and engage its flanges 14 with the edges or flanges of said tube. Then thus applied, the tire is placed upon the rim and the hoops 5 or the ring 22 then adjusted, as shown in Figs. 2 and 3, so that the anges 14 will be clamped in position with the tire. By reason of this construction no metallic hooks or other fastening devices are necessary for retaining the protector in position. The rivets 17 upon each side of the protector serve to effectively protect its side portions troni wear and also to effectively secure the edges oi the outer layers of the protector upon its inner one.

Having thus described my invention what I claim and desire to secure by Letters Patent is A pneumatic tire having an youter protecting covering composed of layers of material,

annular rows of rivets connectingthe tread portion of the layers and arranged 1n stagv gered relation, said rivets having outer enlarged iattened heads disposedout ot transverse alinenaent and on. lines between each other, an annular series of rivets connecting the layers at each side of the tire and between the tread portion of the tire and rim of the wheel, said rivets having outer rounded heads of smaller diameter 'than the heads of the tread rivets, said round headed rivets being arranged in alined longitudinal and transverse rows in close relation to each other so as' to forni clusters of projections to protect the sides of the tire and layers from Wear.`

In testimony whereof I hereunto my signature in presence of two witnesses.
